WAVERTF: (Wave Reflection, Transmission, and Forces) Wave Propagation over Obstacles and Irregular Topography. User's Manual

摘要

A hybrid element method is developed for the calculation of reflection, transmission, and hydrodynamic forces of water waves passing a finite near field involving obstacles and a sea bottom of irregular geometrical configuration. The obstacles may represent fixed floating and/or submerged marine structures, and the sea bottom may consist of undersea mounts, reefs, and trenches. In the far fields, water depths are assumed constant but not necessarily equal. A variational principle with a proper functional is established such that the matching conditions are satisfied along the common boundaries of the near and far fields. The examples are presented and compared with laboratory data and numerical and theoretical results. The WAVERTF computer program and user's manual are presented. An example problem is also included.
